Title: Glider tow-rope with detachable connectors - has rated breaking point and uses knots in strands to hold rope in socket with eye held by shearing pin
Inventor: TOST HANS
IPC: B60D1/18
Filed: 1978-08-21
Abstract: The glider towrope with detachable connectors and rated breaking point uses a textile rope (2) with a soft-plastics abrasion preventing sleeve (3). The rope ends are passed through a rubber anti-kinking sleeve (8) and a cylindrical socket (5) with well-rounded shoulders (6, 7). Knots in the individual strands (4) retain the rope in this socket, which at its open end has drillings (11) for a pin (12) of rated shear strength holding a plug (14) with a connecting eye (17). The anti-kinking sleeve tapers from one, cylindrical, end (9) covering the socket to the other, thinner walled and a tight fit around the rope sheath.

Title: Secondary contamination prevention in sterile filter tests - by filter with hydrophobic and hydrophilic layers on sterile side
Inventor: PETT MANFRED
IPC: B01D35/00
Filed: 1978-10-10
Abstract: A secondary contamination of sterile filters and sterilised particle filters during a test for diffusion and/or bubble point is prevented by a test filter on the clean side of the sterile filter. The filter area of the test filter is such that it prevents a ssec. contamination; one layer of it is hydrophobic and the other is hydrophilic. This is a simple method of saving elaborate precautionary measures; the test procedure continues under absolutely sterile conditions.

Title: Knitter stitch transfer needle - has spreader spring support to ensure take=up needle passage
Inventor: MESTRE MAS MATIAS
IPC: D04B15/02
Filed: 1978-11-04
Abstract: The needle to transfer stitches on a knitter, in the mfr. of tricot fabrics, has the spring mounted on those sides of the needle to spread the stitch loop, in front of the recess to allow the take-up needle to pass through. There is a guide wall to support the take-up needle, so that there is a guiding action for the needle up to the exact transfer point. The design gives a positive and accurate action, without risk of the spring being compressed by the stitches, to hinder the passage.

Title: Cleaning and cooling castings coated with foundry sand - in conveyor trough subjected to both vertical and transverse components of vibration
Inventor: SCHARMER WOLFGANG DIPL ING
IPC: B22D31/00
Filed: 1978-12-11
Abstract: The plant consists of a trough with a semicircular cross-section; and the castings travel along the trough towards a sieve sepg. the sand from the castings. Both vertical and transverse components of vibration are applied to the trough, so the castings are cooled and freed from sand as they travel between the inlet and outlet ends of the trough. The trough may alternatively consist of a tube, and in either case may be fitted with additional cooling devices, esp. nozzles employed to spray cooling wate onto the castings. The trough or tube may also have a double wall forming a cavity fed with cooling water or other cooling medium. The cpd. vibration compels the castings to follow a helical path so intensive cleaning and cooling are achieved.

Title: Switching system for lights of model railway vehicles - uses arm with magnet operated by axle and acting on reed switch
Inventor: SIHLER HELMUT
IPC: A63H19/20
Filed: 1979-11-28
Abstract: The switching system is for changing over the lighting circuit when the direction of the train movement is reversed. A bush (2) is a light friction fit on one axle (4) of the carriage or vehicle. The bush is provided with an arm (1) which carries a permanent magnet (8). Fixed to the carriage chassis is a reed switch (5) wired into the circuit for the exterior lamps (9,10). When the axle turns the bush and arm are carried with it to one extreme stop position or the other, depending upon the direction of rotation of the axle. In one position the magnet is close to the reed switch and causes its contacts to change over and light the appropriate lamps (9). In the other position, the magnet is away from the switch and the contacts return to the normal state, closing the circuit to the lamps at the other end (10). Only a slight friction effect is required to turn the bush. This can be provided by a coil spring (3) bearing against a wheel and a shoulder on the bush, or by friction between bush and shaft.

Title: Gate supply for regulating transistor derived from vehicle battery - comprising voltage multiplier and limiter to provide constant potential source
Inventor: CONZELMANN GERHARD DIPL PHYS
IPC: H02M3/07
Filed: 1979-12-07
Abstract: The regulating transistor is a MOS type power device. To provide the required constant and sufficiently high gate voltage a voltage multiplier is connected between the widely varying main power supply (U1) for the vehicle and the transistor gate. Typically the voltage multiplier circuit comprises an oscillator driving a switching transistor (11). The resulting chopped output is applied to a conventional diode and capacitor multiplier which terminates in a smoothing capacitor (21). The multiplier can be with advantage made as an integrated circuit of the n-channel MOS type, and thus be part of the regulating transistor chip. The oscillator may be one used in common with other circuits on the vehicle. The output voltage (U2) of the multiplier is normally regulated, for example by a Zener diode.

Title: Floor, wall or ceiling surface with heating system - contains metal pieces shaped as hollow bodies hovering in position
Inventor: BECK EDGAR DIPL ING
IPC: E04F15/12

Title: Water steriliser for dental surgery - with metering pump feeding on demand sterilising soln. to water pipe
Inventor: CISZEWSKI HANS-JOACHIM ING GRA
IPC: C02F1/68
Filed: 1980-07-28
Abstract: An appliance for the sterilisation of water, esp. for cooling and flushing purposes in conjunction with dental surgery instruments, consists of a container for a sterilising soln. such as silver nitrate and a metering pump which supplies the soln. under pressure to a pipe leading to to donsumer, when a control unit turns it ON.

Title: Dosing liquid components of cosmetic preparations without motor - using pressurised gas container in supply jar cap
Inventor: WITTERSHEIM ADAM
IPC: G01F11/32
Filed: 1980-08-18
Abstract: The dosing device for liquid components of cosmetic preparations feeds the components from a supply container of relatively large capacity into a container or device in which they are put to further use. This is achieved without a complex and expensive electric motor drive. A gaseous driving medium is used in a way that allows the supply container (12) to remain unpressurised and results in only a small quantity of the gas being used during each dosing operation. The pressurised gas container (30) fits in a cap (14) in the neck of the supply container. It is connected (20) to a dosing container (16) in the base of the supply container which is also connected (22) to a delivery connection (42) via which the components leave the system. A control shaft (18) with a dosing vessel (16) sealing piston (50) has a weaker spring (58) than that holding the gas container (30) valve closed.
